This API was added to libfprint to allow drivers to report the match result early before the operation has been completed. No driver makes use of this facility yet and instead drivers try to finish the operation early for quick result reporting. This primarily means not waiting for finger removal. Once drivers are updated, fprintd reactivity will regress unless the early match callback is implemented as they would only get an operation finished callback when the whole of the operation was finished, including finger removal and finishing up USB communications.

fprintd ======= https://fprint.freedesktop.org/ Daemon to offer libfprint functionality over D-Bus Might eat your kangaroo. Written in C. Licensed under the GPL version 2 or any later version (see COPYING). A PAM login module is included in the 'pam' directory. API use cases ============= - User wants to use the fingerprint reader, and enroll his fingerprints, or remove some fingerprints from the database - Administrator wants to enroll fingerprints for a particular user, or remove fingerprints for a particular user - Laptop/desktop authentication: * Check for fingerprint devices * Check whether a particular user has any fingerprints enrolled * Verify a fingerprint for a particular user, or, if the device supports it, verify that the fingerprint matches against any of the fingerprints enrolled - Point Of Sale authentication (in a bar, the fingerprint reader is used to see who accesses a particular point of sale/till, in place of PIN code authentication and/or tokens) * Given a list of users, verify which one has scanned their finger
